DIFFERENTIAL PRESSURE SENSOR (for DPF) ON-VEHICLE INSPECTION


  1. CHECK DIFFERENTIAL PRESSURE SENSOR ASSEMBLY


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / DPF Differential Pressure.

    5. Slide the clip and disconnect the No. 6 exhaust pipe air hose from the differential pressure sensor assembly.

    7. Check the pressure value of the differential pressure sensor assembly.

      Standard pressure
      Approximately the same pressure as the applied pressure indicated on the GTS.

      Tech Tips

      Perform the inspection by applying a pressure within the range of 0 to 98 kPa (0 to 1.0 kgf/cm2, 0 to 14.2 psi).
